Good for the environment?
LCD's are very deceptive. The use phase of the LCD and CRT is negligible compared to the costs during manufacturing:
Due to its' complexity, during manufacturing an average 17" LCD requires:
3.7kg Photolithographic and other chemicals
5.9kg Elemental gases (N2, O2, argon)
87kWh electricity
198kg direct fossil fuels (98% natural gas)
226kg Embodied fossil fuels
1,290 litres water.
"ouch" - Mother Earth.
During manufacturing an average CRT requires:
0.5kg Photolithographic and other chemicals
0.2kg Elemental gases (N2, O2, argon)
21kWh electricity
3kg direct fossil fuels (100% oil)
9.5kg Embodied fossil fuels
450 litres water.

The $200 you'd save buying a similar sized CRT will more than offset the electricity savings you'd achieve during the lifetime of the monitor. Plus CRT's are much easier to recycle.
